Application :filed April 11,

To all whom it may concern-. ,y

Be it known that I', EDWARD. Gf SONNE- MANN, a citizen of the United. States, residing at St. Louis, Missouri, have inventedav certain new and useful Improvement in VVindow-Operating- Mechanism for Vehicle Doors, of which the following isa full, clear, and exact description, such asl will enable' .others skilled in the art to which it appertains to make and use the same.

This invention relates to devices ofthe character that are used on automobiles and' other vehiclesrequipped with closed bodies for raising and lowering the windows that aie slidingly mounted in the doors of the body.

. Themain object of my inventionis to provide a window operating mechanism for vehicle doors that is inexpensive tomanu- Vfacture and install, easy to opeiate and of such design that it vis-.not' liable` to( get out of order when inuse.

Figure 1 is a vertical sectional view of a vehicle door equippedwith a window oper-V ating mechanismjconstructed in. accordance with my invention.

Figure 2' is a front elevational view of 1 my improved window operating mechanism.

Figure 3 is `a detail view, .showingthe cam on the operating shaft in? the .position it occupies when .the window of the door is closed.

Figure 4 isa detail` view, showing how said -cain raises the window sufficiently to disengage the two ccp-.operating interlocking portions onV the window sash and on the door.

Figure 5 is a detail view, showing how Vsaid cam drawsthe window sash.` inwardly with i relation to'. the door-sufficiently to Vpermit the sashto 'move downwardly (into thev pocket in, the door.

Figure 6 isa detail view, illustrating the cani on the operating shaft in the position it occupies just before said cam passes out of engagement with the parton the -window sash with which said cam cog-operates; andV Y Figure 7 is atop theoperating shaft. Y I

Referring to the drawings which illustrate the preferred form of my invention, Ades-y igiiates a vehicle doorof the kind usedon closedfveh'icle bodies; 'BJ designates a window sash Yslidinglyr mounted-in said door andadapted to be lowered: intoa pocketin plan view.'V of'the cam on Speccatoncof Letters 1atent.

window, C designatesa substantially hook-i shaped device arrangedtransversely ofthe D designates' a. verticallydisposed yflange window sashV at the lower edge of 'sa-maand that extends transversely ofthe door at'the upper edge ofthesash pocket and which cooperates`V with the hook-shaped device C on the sash to sust-ain the sash in its elevated f position when the window'is closed. yThe parts. A, B,' C and D are ofconventional construction and may be formed in-various ways without departing from the spirit lof -the sash B and for movingthe ho'okfshap'ed device C on said sashkinto and outofen- 'gagement with the part D on the door with Vwhich said device'C (3o-operates,` to sustain the sash' in itsA elevatedV posit-ion. Said-Y mechanism preferably comprises Va verti-v' A callyv disposed operating shaft 1 'having its upper and-lower ends journaledin `suitable' bearingsQ on the door, only the upper bear-l ing Vbeing shown, a worm 3 o n saidyshaft, a nut 4' cooperat-ing y with said worm` and operatively connectedl with'the window sashV B, meansfor rotating-the shaftfl in oppo@ site directions, such, for example, asa *bev`u eled gear 5 mountedon the door, and a bev'-v eled' gear 6A on. the,Y operating shaft'rthat meshes with the gearY 5,.the1 gear 5 being equipped with a handle or. other suitable device 7 by which said gear-may be rotated, and means separate anddistinct from said worml and nut 3 and 4, respectively, for moving the sash B relativelyfto theV door A' in such a manner as to engage and disengage' the co-operating interlocking portions Gand D on the sash and door.

' ln the form of my invention herein illusj trated the'means 1j ust'referredto consistsof a cam E rigidly connected to the operating shaft l preferably at apoint slig'htlybelow` thegear 6 onzsaid shaft, and Van'inwardlyprojecting arm F atvthe lower 'edge` of the A i windo-w sash thatjcooperatesrwith tliecain` E. The cam E isrprovided with aninclined if i topi.` face thatfco-operates with the-1in'- vwardly-projectiiig arinv F on the window" sash and which-is of such forni `that it'wlill'fi* raise and-lowerlthe sash slightlywdiiring' YfcoiiipleteY revolution'o'f said' cam, :and saidy cani.. VE is also provided'` with 'a5v substantiallyj eccentric groove y that'rec'eives" adepen'd? 'ing' projections oir-ftheinnereiid of' the" arm F as shown more clearly in Figures 3 to 7, inclusive, the function'otsaid groove and projection y ande, respectively, being to move the sash B inwardly and outwardly with relation to the door, so as to shift the hook-shaped device C on the sash into and out of the vertical plane in which the cooperating device D on the door lies. rIhe nut 4 previously referred to through which the worm 3 on the operating shaft passes is provided with a horizontally-disposed shank or projection 4.y as shown in Figure l, that projects outwardly, and the window sash B is provided at its lower end with a depending plate 8 having a vertically-disposed, elongated slot 8a therein tor receiving the horizontally-disposed shank or projection 4a on the nut 4, thus providing a connection between the window sash and the nut 4 which permits the sash 4to move longitudinally slightly withA relation to the nut 4 when the sash is being` moved by the cam E on the operating shaft, as hereinafter described.

`When the sash is in its closed position with the hook-shaped device C thereon in interlocking engagement with the transversely-disposed liange D on the door, the parts of my improved sash operating mechanism occupy the position shown in Figures l and 3, the depending projection of the inwardly-projecting arm F on the sash beingpositioned at one end of the eccentric groove y in the cam E. When it is desired to lower the sash B into the pocket in the door A the handle or operating device 7 ol the gear 5 is turned in a direction to move the cam E into the position shown in Figure 4, the inclined or spiral top surface a: of said cam causing the sash to move upwardly with relation to the door sutliciently to disengage the device C on the sash 'from the co-operating part D on the door. As the rotary movement of the operating shaft l is continued the eccentric groove 1/ in the cam Ecauses the lower edge portion oi the sash B to move inwardly relatively to the door suiliciently to carry the hook-shaped device C on the sash out of .the vertical plane of the co-operating part D lon the door, as shown in Figure 5. Further rotary movement of the operating shaft 1l in this same direction causes the sash B to move downwardly into the position shown in Figure 6, due, of course', to the shape oi the inclined top face w of the cam E. lVhen the cam reaches this position the depending projection e on the army F is positioned at the opposite end of the eccentric groove y in said cam, and consequently, the further rotary movement of the operatingshaift in the same direction causes the armF to passV out of engagement with the cam E, and thus bring the nutf4'into service. In other words, during the first portionof the operationof lowering the sash the movement of the sash with relation to the door is effected by the cam E on the operating shaft and the arm F on the sash, but attersaid arm has passed out of engagement withsaid cam, the weight ot the sash will he sustained by the laterally-projecting shank 4 on the nut 4, and consequently, the Vsash will be moved downwardly into the pocket in the door by the movement imparted to said sash by the nut 4.

To raise the sash the operating handle 7 on the gear 5 is rotated in the opposite direction, so as to cause the nut 4 to travel upwardly on'the worm 3 on the operating shaft, and when the sash reaches a cert-ain height the depending projection .a of the arm F on the sash enters one end ot the eccentric groove y in the cam E. rllhereafter, the rotary movement of said cam causes the sash to be raised to such a position that the hook-shaped device C on the sash is higher than the co-operating part D on the door, to be thereafter moved outwardly so as to bring the device C into the vertical plane of the device D on the door and to thereafter be moved downwardly so as to bring the device C into interloclringv engagement with the part D on'the door.

A window sash operating mechanism for vehicle doors of the construction above dcscribed is inexpensive to manufacture and install, and as it is composed ot only a few rugged parts of simple design, it is not liable to get out of order when in use.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent, is:
